Abstract
Second harmonic generation of higher-order Bessel beams (Bessel vortices) f ormed by axicon was investigated in KTP crystal. A splitting of frequency-d oubled Bessel vortex of topological charge 2n, n = 1, 2, 3, into 2n single- charged vortices was observed. The phenomenon is caused by copropagating ze roth-order Bessel beam acting as coherent background. (C) 2000 Elsevier Sci ence B.V. All rights reserved.
